How did Det. Isom know so quickly from where to fetch Wendi Adelson the day of the murder?
In the US, the physical location of a working (or enrolled at a university) adult would be known within about a couple of hours at most, under normal circumstance when the person is not hiding. One of the multiple tools for so doing is “phone pinging”.
Major Police Departments have their own pinging devices from about 2005 on-ward, which allow them to by-pass the need for pinging help request from cellular service providers. It takes at most 12 pings to find the location of any phone.
In actuality, it takes much less than 12 pings. For example, if with 1 single ping of a MD’s phone you find the closest tower nearby a hospital, you know that she is at work. If after 3 pings you find someone’s car at a strip mall by a restaurant, you infer “Voila! She is eating.”
